TO AALL WHOM IT MAY CONCERN: I

Be it known that I, JOHN W. HUTCHINGS, of Bridgeport, in the county ofFairfield, and State of Connecticut, have invented a new and usefulimprovement in Window-Sash Supporters; and I .do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing -had to the accompanying drawings, forming part of thisspecification, in whichp Figure 1 is a front view of a window-frame 'andone sash having my invention applied to them.`

Figure 2 is a vertical section of the same, the sash being down.

Figure 3 is a similar section, the sash being partly raised.

Figure 4 is a horizontal section of the same in the line x l:z: of g. 1.

Similar letters of reference in the several figures indicatecorresponding parts.

The object of my invention isltwofold: iirst, to insure a more perfecthold upon thc sash when raised;

second, to avoid marring the face of the sash by the contact of thesupporter with the Wood` and the paint.

The 'nature of my invention consists in applying the wellknown cam orlevereecentric sash-supporter to the window-frame in such a manner thatit binds upon a plate applied to one of the retaining strips of theframe instead of directly upon the sash, and as said strip is notfastened by screw or nails to the frame except at its two extremities,it is deflected by the action of the eccentric from a straight line andmade to bind along a considerable portion ofits length upon the sash,and thus e`ectually prevent it slipping down so long as thelever-eccentric or cam is acting upon the strip. A i

To enable others skilled in the art to make and use my invention, I willproceed to describe its construc tion and operation with reference tothe drawing. A

A represents the sliding-sash; B the strip used to keep the sash in itsplace; C is the eccentric attached to -a plate, D, which is made fast tothe casing or framing E, and is partly covered by the strip B, as shown.It will be seen that when the eccentric is in the position shown in iig.3, it presses the strip tight against the face of the sash and preventsit from moving. But when thc 'ececntricnis in the position shown infigs. 1, 2, and 3, it ceases to bind on the strip and the sash is freeto be moved up and down. The strip is put on so as to be capable ofspringing or bowing at its middle, being fastened only at itsextremities, as shown at a a. The metal plate F is applied to the stripat the point where the eccentric bears in order to prevent injury t'thewood and paint of the sash.. Now, I have seen cams and' eccentric-leversfor sash-supporters, but I believe they `have never;` been used in themanner I have described .and shown, such cams usually pressing orbearing directly on the face of the sash, whereas my cam oreccentric-lever enables me to use the stripitself to hold the sash,which strip presents a long binding surface to the sash, and therebyinsures a perfect hold upon the sash when the sash is elevated. Thestrip will also prevent the sash rattling when the sash is down, if thep eccentric is press-ed against it.

What I claim as my invention, and desire to secure by Letters Patent, isI, The combination ofthe strip B and eccentric or cam-lever C as asash-supporter, substantially as and for the purpose described.
